Math problems found in the GED exam cover both basic and advanced algebra, averages and rounding, basic operations, sequences, exponents, fractions, square roots, geometry, graphs, measurements, percentages and ratios. According to Kentucky Adult Education, test takers most commonly make mistakes on math problems covering geometry and measurements, reading and interpreting graphs and tables, applying basic math principles and solving problems with mathematical reasoning.
Math problems covering geometry and measurements may ask students to determine the measurement of an angle based on the given measurements of other angles in the shape. Another question may ask students to determine the length of the base of a right triangle given the lengths of the hypotenuse and the other leg. Questions covering graphs may ask students to select the appropriate graph based on a written description. In this section, students may also be required to sketch a graph to illustrate a changing value. For problems covering basic math, the test may ask students to determine percentages based on a word problem. Problems may also ask students to interpret and apply algebraic expressions. Other basic math questions may require students to plug a number into a formula and determine the solution. The GED test may ask students to use fractions while completing some of these problems.
